Sensitivity to mercury appears to be not uncommon and perhaps the commonest contact with mercury in the general population is by amalgam dental restorations. Recently, we have experienced 2 cases of mercury dermatitis following amalgam dental restorations which were confirmed by the patch test. We report our cases with the patch test results and review the literatue on previous reports.

We report 2 cases who have been diagnosed as lipodystrophia centrifugalis abdominalis juvenilis. The case 1 is l2 year-old girl. She had well-defined depression of skin on both inguinal area, lower portion of chest and both flanks which was noticed at the age of 7. The case 2 is 16 year-old boy with depressed lesions on Rt. inguinal area and abdomen which were noticed at the age of 6. Biopsy specimen showed absence of subcutaneous fat tissue in both cases.

The present study was performed to evaluate the comedogenicity of several cosmetic ingredients, vegetable oils, steroid and sulfur. The test materials were applied to one ear canal of rabbits for 6 weekdays for 2 weeks. The results were as follows: l. Among the 14 cosmetic ingredients, no comedogenicity was shown in propylene glycol and petrolatum, mild comedogencity in squalene, acetylated lanolin, polyethylene glycol, cetyl aIcohol and Tween 80. Propylene glycol, sodium lauryl sulfate and oleic acid showed moderate comedogenicity. Severe comedogenicity was observed in myristyl myristate, isopropyl myristate, butyl stearate and myristyl lactate. 2. Moderate to severe comedogenicity was shown in olive oil, sesame oil and corn oil and moderate comedogenicity in sulfur (8%) and betamethasone dipropionate (0.06%) R. Histopathologic grading were paralleled the findings of the naked eye.

So-called, the double channel pylorus has been, relatively rarely, reported through out the world. All reported cases were almostly those of gastroduodenal fistula as a complication of peptic ulcer disease. The congenital forms of double pylorus were reported even more rarely. We found three cases of double channel pylorus in 25,000 cases endoscopy done at our unit. All those three cases were thought to be acqired form endoscopically, radiographically and histologically. One of those was undergone to operative resection because of uncontrollable bleeding and the others were on medical theraphy with satisfaction.

Few reports exists citing a case of a retropharyngeal bronchogenic cysts. In this study, we report a bronchogenic cyst with a cystic appearance observed in the retropharyngeal space.

Recently, we experienced two cases of tuberous sclerosis, in 4-year-4-month-old female and 17-month-old male patient. The diagnoses were established by typical clinical manifestations and brain CAT. Especially, in latter case, calcific density was successfully detected by brain CAT, while plain radiographs of the skull revealed still no evidence of calcification. A brief review of related literatures was made.

Pulmonary siderosis is one kind of pneumoconiosis caused by the long term inhalation of iron dust. Iron is deposited in the lungs, usually in the form of iron oxides. Iron oxides are relatively inert particles with a minimal fibrotic response. It occurs in a number of occupations including welding, steel rolling and grinding, casting, iron ore mining and oxyacetylene cutters. We have experienced the first case of pulmonary siderosis in Korea. A 42-year-old woman who had engaged in a metalware manufacturing factory as a manager for 7 years was admitted because of dyspnea on exertion. A pulmonary function test disclosed a mildly obstructive ventilatory defect. Open lung biosy revealed deposition of iron-laden macrophages in most alveolar spaces by which confirmed the diagnosis of pulmonary siderosis. We report a case of pulmonary siderosis with a review of the literature.

OBJECTIVE: To evaluate the postoperative laryngeal CT findings of neoarytenoid soft tissue at an arytenoidectomy site during a supracricoid partial laryngectomy, and to compare its thickness to the mucosa over the spared arytenoid cartilage. MATERIALS AND METHODS: Thirty-one patients underwent a supracricoid partial laryngectomy with (n = 14) or without (n = 17) an arytenoidectomy. A postoperative laryngeal CT examination was performed to statistically compare the thickness of the neoarytenoid soft tissue to the mucosa over the spared arytenoids. RESULTS: The neoarytenoid soft tissue revealed an eccentric prominence in all 14 arytenoidectomy sites. Further, the neoarytenoid soft tissue was consistently thicker than the mucosa over spared arytenoids cartilage (p < 0.01), however did not exceed 11 mm. CONCLUSION: The eccentric prominence of neoarytenoid soft tissue at the arytenoidectomy site during a supracricoid partial laryngectomy should be identified and distinguished from a recurrent mass when compared to spared arytenoid cartilage on a postoperative laryngeal CT.

OBJECTIVES: The purpose of this study was to investigate(1)the differences in the sleep pattern, job satisfaction, the quality of life between the rotating shift work nurses and the nurses on a fixed day schedule and (2)the effects of the individual(circadian rhythm and personality)and the work system factors on the job satisfaction and the quality of life. METHODS: Sleep Questionnaire, Korean translation of Composite Scale(KtCS) Job Satisfaction Index, General Health Questionnaire, Eysenck's Personality Questionnaire were administered to 85 rotating shift work nurses(the rotating group)and 70 nurses on a fixed day schedule(the daytime group) We compared the weekday sleep pattern, the frequency of sleep disorders during the last month, circadian rhythm patterns, job satisfaction, and the quality of life between the two groups. Also, we conducted the stepwise multiple regression analysis, where the independent variables were circadian rhythm, work schedule, extroversion, and neurotism and the dependent variables were the job satisfaction and the quality of life. RESULTS: Between the two groups, there were significant differences in the sleep pattern including the regularity of sleep and the frequency and duration of naps. The rotating group had more frequent sleep problems, poorer job satisfaction and quality of life as compared with the daytime group. The job satisfaction and quality of life were poorer in the nurses who were on a rotating shift work schedule and who had higher neurotic trend. On contrary, The job satisfaction and the quality of life were better in those who were on a fixed daytime shift work schedule and who had more an extroversive trend. However, the circadian rhythm had no significant effect on the job satisfaction and quality of life. CONCLUSIONS: The sleep pattern, job satisfaction, and the quality of life were significantly poorer in the rotating group than in the daytime group, as expected. In terms of individual factors which determine the job satisfaction and quality of life, the personality dimensions had a significant effect, whereas the circadian rhythm did not. These results suggest that the circadian rhythms of shift workers may be realigned and that personality characteristics may be an important factor in coping with shift work.
